Summary: Enables phospholipid binding activity. A structural constituent of nuclear pore. Involved in nucleocytoplasmic transport. Located in nuclear periphery. Part of nuclear pore central transport channel and nuclear pore nuclear basket. Human ortholog(s) of this gene implicated in primary biliary cholangitis and striatonigral degeneration. Orthologous to several human genes including NUP62 (nucleoporin 62). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Cytoplasmic Masking of Hydrophobic Residues of FG Repeats
Title: In-Cell NMR within Budding Yeast Reveals Cytoplasmic Masking of Hydrophobic Residues of FG Repeats.
Nsp1 releases a barrier that otherwise prevents nuclear pore complex passage through the bud neck to daughter cells.
Title: The transmission of nuclear pore complexes to daughter cells requires a cytoplasmic pool of Nsp1.
Nic96 without its N domain binds in vitro to Phe-GLy repeats of the Nsp1-Nup49-Nup57 complex, suggesting how Nic96 could organize a transport module with coiled-coil domains and FG repeats in the central pore channel.
Title: Structural basis of the nic96 subcomplex organization in the nuclear pore channel.
findings show that phenylalanine-mediated inter-repeat interactions cross-link FG-repeat domains into elastic and reversible hydrogels; evidence obtained that such hydrogel formation is required for viability in yeast
Title: FG-rich repeats of nuclear pore proteins form a three-dimensional meshwork with hydrogel-like properties.
